To be very honest, when I posted a few days ago, Oracle Database 19c is certified on OL8/RHEL8 I didn’t check for the Oracle Clusterware (OCW) certification. I blindly assumed that this is the case. But from comments and discussions on twitter, I realized it may be necessary to point this out explicitly to avoid confusion. Even though my fellow mate, RAC Product Manager Anil Nair has pointed it out already many times: Of course, Oracle Clusterware is certified on OL8/RHEL8 as well.

Find it on MOS
Your source for certification information for Oracle products is MyOracle Support. Hit the “Certification” tab.
As you see, there is a separate Product “Oracle Clusterware“. And once you choose “19.0.0.0.0” as Release, you will get the Platform options OL8 (marked blue) and RHEL8 (two lines above OL8).
So yes, you can have OCW 19c on OL8 and RHEL8. And the fine print says:
- For OL8, it has to be Update 1 or newer (i.e. 8.1, 8.2 etc)
- Minimum RU is 19.7.0
- Minimum kernel versions:
- Oracle Linux 8.1 with the Unbreakable Enterprise Kernel 6: 5.4.17-2011.0.7.el8uek.x86_64 or later,
or - Oracle Linux 8.0 with the Red Hat Compatible kernel: 4.18.0-80.el8.x86_64 or later
- Oracle Linux 8.1 with the Unbreakable Enterprise Kernel 6: 5.4.17-2011.0.7.el8uek.x86_64 or later,
And some people really tested it right away ๐ Very cool!

Just waiting now to see if EBS R12.2 application tier and EBS database tiers are certified for OEL8 and when is the preinstall RPMs for EBS and DB available in the OEL8 addons repo
Hello!
I am an Oracle engineer in Japan.
“Oracle 19c (19.7) Clusterware is certified on RHEL8”
I want to know the pre-requisite PKG in RHEL8 installation requirements, but no info anywhere.
ใปDatabase
ใปGrid Infrastructure
Help me. please tell me.
Hi Manabu-san,
I did a deep check on MOS, but I only found this note:
Oracle Support Document 2668780.1 (Requirements for Installing Oracle Database 19c on OL8 or RHEL8 64-bit (x86-64)) can be found at: https://support.oracle.com/epmos/faces/DocumentDisplay?id=2668780.1
Which is for the database only, and explicitly says, it does not cover GI.
So for the database, this will help you.
But for GI, you may need to open an SR please and check with Oracle Support.
Thanks, and kind regards,
Mike
But still no AFD support for OL8.x…sigh….any clue if/when that is coming?
No, you will need to bother Oracle Support with this please.
Cheers,
Mike
Hi Mike, do we have ASMlib packages for OL8?
I am not able to find them, with el7 packages i am not able to get working asmlib on OL8,
my system is on Azure: 4.18.0-147.8.1.el8_1.x86_64
Hi Daniel,
please open an SR and check with Oracle Support. I have seen mixed messages (people using the lib from OL7 with success) but not sure what’s right or wrong.
Cheers,
Mike
Hi Mike!
There are different messages written about 19.8 and RHEL8.2. I am constantly getting the “AFD-620: AFD is not supported on this operating system version: ‘unknown'”-message. Someone is saying 82 is not supported?
Hi Kurt,
does this happen during the installation on 8.2?
Then try with ./runInstaller -ignoreSysPreReqs
As far as I’m aware (and this is what the official information on MOS says), 19c (and this includes all RUs unless otherwise stated) is supported on RHEL 8.2.
Cheers,
Mike
Mike, -ingnoreSysPreReqs is not a valid option for the gridSetup.sh. Here is what is happening:
/u01/app/oracle/product/19.0.0/grid/gridSetup.sh -silent -responsefile /home/oracle/gridsetup19.rsp
Launching Oracle Grid Infrastructure Setup Wizard…
[FATAL] [INS-41223] ASM Filter Driver is not supported on this platform.
ACTION: To proceed, do not specify or select the Oracle ASM Filter Driver option.
*ADDITIONAL INFORMATION:*
– AFD-620: AFD is not supported on this operating system version: ‘unknown’
It would be strange if they support GI without AFD as AFD is told to be a very good thing when it comes to reduce of IO’s against the disks where the ASM resides.
I did create a SR yesterday and then we will see what comes out of that
Thanks Kurt – I didn’t try it – thanks for the update.
Cheers,
Mike
Did a SR at this spesific problem:
Answer 1:
“…..you can apply patch 31643145 to fix this issue”
Did not work as this end up in conflict. Did a reply with output and so on
Answer 2:
“AFD is currently not supported on any version of Linux 8 you will have to use Linux 7 or not use AFD”
Typically workflow in MOS. They suggest a solution and say nothing about the feature is not supported. Further on after spending more time with it they state that this is not supported ๐
By the way – the Certification says RHEL8 is supported, but sas nothing about the AFD.
Well….. better wait with this plattform ๐
Did a SR about this matter and firstly they asked me to install a patch, but as this patch ended up with conflict they told me that AFD is not supported in RHEL8.
AFD is told by Oracle to limit IO-request against disks and because of that it is improving perfomance. It is supposed to replace ASMLibs which has not been developed or updated sonce long time ago.
MOS said the solution is not to use RHEL8 and go back to RHEL7. Arrogant as always ๐
Interesting that a certified product is does not include the out-of-the-box-stack.
Hi Kurt,
I see the dilemma ๐
But I couldn’t get more information about it internally either.
Thanks,
Mike
